Abstract

PROBLEM TO BE SOLVED: To improve an appearance and finger touch feeling, the, by displacing backward the surface on the boundary side of at least one side of partial lenses welded with each other as the surface approaches the boundary. SOLUTION: The boundary 5 side end part 3b of the surface 3a of a partial lens 3 is formed into a slope backward displacing as it goes to the boundary 5. When two partial lenses 2, 3 are welded, for example, welded by a vibration welding method, at first mutual joint end parts are brought in contact with each other. Namely, the extreme end face of the welding leg 8 of the partial lens 3 is brought in contact with the joint leg 6 of the partial lens 2. Vibration is applied to one or both of the partial lens 2, 3, and the mutual contacted parts of the welding leg 8 of the partial lens 3 and the joint leg 6 of the partial lens 2 are melted and integrated. Directly after the welding leg 4 of the partial lens 2 abuts on the joint end face of the partial lens 3, vibration is relased, and the abutting part of the welding leg 4 becomes in a little melted condition.

互いに溶着された部分レンズの少なくとも一方のものの
境界部側の表面を境界に近づくに従って後方に変位する
ようにしたことを特徴とする。As is apparent from the above description, the lens for a vehicle lamp of the present invention is a lens for a vehicle lamp in which a plurality of partial lenses are integrally formed by welding.
The surface on the boundary side of at least one of the partial lenses welded to each other is displaced rearward as approaching the boundary.

Inconspicuous, and even when touched with a finger, the original dent has a stronger impact and hardly causes the above-mentioned displacement.
